An ob'ect of the invention is to produce a mixer w ose agitator can Abe comp etely inclosed inforder to pupttect it from bacteria,

u her object of the invention is to rovide quick and convenient means for wa g the agitator.

1 A preferred form of the invention is illustrated in the' accompanying drawings in which l 'Figure 1 is a front elevation of a drink mixerY partly broken away, constructed in accordance with the invention, with the agitator covered and being washed Fig. 2 is-a similar elevation with the mirer ready for use; v

3 is an enlar ed side elevation showf in e cap part of Y e cover;

ig. 4 is a perspective view of the end of the spray tube; l A

Fig. 5 'is an alternative shape of spray tube; and v Fi 6 is a detail of one of the straps whic `support the cover.

All esta A ploy drink mixers in whic a vertical agitator rod is rotatedby 'a small motor whose axis is parallel' `to that of thej agitator. After the mixer has, been used, the agitator is covered with a iilm' of the li uid which has just been mixed, and in a dition has large drops adhering to its lower part. This is objectlonable in that the' liquid attracts' lles and furthermore,`the liquid from one remaining upon the agltator normal- 1 becomes mixedwith the next. No practical means has heretofore been known for cleanin the 'agitator and protecting it from dirt an Bies whennot in use.

The novel construction which will now be described keeps the agitator completely covered when not'in use and can also be availed of effectively to wash the agitator in' a sanita manner. This mechanism is simple an can be operatedv with ease and rapidity. It is not necessary -for the operator to touch the agitator or wet his hands inl any manner.

vIn the preferred form illustrated, a base carries a support 11, at the top of which a vertically immovable motor 12 is carried. Associated with the motor is the usual shaft 13, 'to which is attached an agitator 14 having a tip 15 at its end. A cable 16 connects the motor with a source of current.

The mechanism inclu'des a collapsible coverfor'the agitator and spray means for lishments sellin 4soft drinks eni-` washing the latter. The cover consists of telescopic sections 17,- and a funnel shapedcap 18, with a holein its apex, and is suspended yfrom the motor 12 by straps 19. These straps are constructed of 'resilient metal and are riveted t9 the^ uppermost of the telescopic sections as shown in Fi 1 and .2 of the drawings. .The straps ave slots with enlarged heads as shown in Fig. 6. To attach the cover, the enlarged heads of the slots in the strap'sare passed over the heads of bolts in the motor, 'and the casinv pressed Vtightly up against the motor thls bending and forcing the stra s out:

ward. The bolts y20 are then ti tened,l

clamping the Straps tight and fastening the Y cover to the motor. Similarly, the cover may be easily detached and removed from association with the motor and agitator.

When extended, the telescopic sections 17 and the cap 18 are designed to cover the a 'A tator completely. The cap is hinged to e section' Vof the cover furthest from the motor, and is desi ed to close the end of the cover below the tlp 15 of the agitator automatical# .ly when the' telescopic sections are extended. .This automatic closure is obtained bymeans of a handle 21 and a Weighted lever 22 on the cap, the' weighted lever lbeing fastened tothe ca 18 near the hinge ointv and tendvingto ho d the same shut. T e handle 21 is fastened to the ca at its free side and extends outwardl om the rim of the cap in asubstanti y straight line. at a downwardly extending angle when the cap closed osition. tions o 'the cover are collapsed an together exposing the agitator, this weighte'd lever 22 en ages a spring clamp 23, mounted on the side of the uppermost or stationary Section, and the cap is thus held clear ofthe agitator. At the same time the cover is held in the collapsed or nested position b means of a catch 24 which can convenient be formed from the lower end 4of one of t e straps 19. This catch 24 is adapted to engage a ange 24 on the lowermost telescopic section.

In order to wash the agitator a spray is introduced at the top of and sprayed upon said agitator. For this purpose va tube 25 is attached to a source of water supply and brought within the casing,`as shown in Fig. 1. In its simplest form this tube is bent in the form of a U, as shown in Fig. 4. It may be desired, however, to bend 1t in the is in When the telesco 1c sec-- nested Tos form of a circle as shown in F' 5. In either vcase the tube is perfora on the inside of the curve as shown so as to throw the spray' against the a 'tatou Water is carried to the bent tube y a pipe 26. A button 27 held in dise ged position bya spring 28 is convencn y provided, for instance on the base of the apparatus, as shown in Figs. 1 and 2. Upon being pres this button opens the water valve, permitting water to ilow through the tube and t0 descend about the agitator-for the purpose described. The valve (not shown) may be of any convenientform such as a -simple transverse lung'er with a hole in it. VThe collapsib e cover prevents vany splashing of the, water, and the hole in the capuermits its escape. This hole ma be ofcient to. pemiit the escape of all water entering the cover, or where preferred it may be made smaller, i. e. 'not large enough to permit passage of liquid as fast as duced by t e spray. Inthe latter case, water will back up ten immerse the tip. 11E esired, the motor may then be turned on, making the a 'tator whirl around in the water and was itself. A drain basin 29 collects the waste water talling from the cap, and is drained from the bottom by a 4Waste pi' 30. y l

The operation of tg; mixer is as follows: A drink having been mixed and the container having been' removed from below the agitator, the handle 21 is ulled downwardly, thus disengaging the ange 24 from the spring catch'24, and at the same time releasing the weighted lever l22 from the spring` The cover sections fall into exvity and the cap asclamp 23.

ment of the wei ht 22 about its hinge.

As shown in ig. 2' the handle 21 lies at such an angle when the cover 1s collapsed that .as soon asthe weightedlever 22 isreleased from the clam -23 -and the cover starts to extend, the andle 21 will vguide the cap 18 around ,the agitator tip 15 into such a position that the weighted ever can close the cap. a.

The agitator is now completely surrounded by the cover and cap and the button 27 can be pressed,opening the water valve and causin the water to descend in a spray upon t e agitator. As described above, the water escapes through a hole in. the ca 18, and is cau ht in thedrain basin 29 w ence it escapes t rough the waste pipe 30.

When the apparatus is not in use` the tator may be protected by the exten ed cover, which need only be removed preparatory to use. The spray, of counse, is used onl when it is desired to wash the agitator.

'IYhe present invention provides ag convenient, quickly operated, and effective means for keeping the agitator of a mixer tojill the cover and` sedin the art.
